NILS M. LAGERGREN, OF PORTLAND, OREGON,

BED.

To all whom z't may concern:

Be it known that I, NILs M. LAGERGREN, a citizen of Sweden, residing at Portland',

-in the county of Multnomah 4and State of Oregon, have invented certain new and useful Improvements in Beds; vand I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which `i=t appertains to make and use the same.

This invention relates to improvements in beds and more particularly to that type kincluding an adjustable head rest.

The primary object 0f the invention is to provide a bed with a -head rest which is adjustable to various angles and whose operating mechanism is easily operated and eX- treniely simple in construction.

Another object is to provide a device of this character in which the mechanism for adjusting the head rest is protected by a casing, and which may be locked aft various points, according to ,the desired angle of the head rest.

in view my invention resides in' the novel features of construction and in the combination and arrangement ofthe several parts as described in .the specification `and claim and clearly illustrated in the accompanying drawings which form a part of this application and in which Figure l represents a side elevation of my improved bed. Y

Fig. 2 is a horizontal sectional view taken on the line 2 2 of'Fig. l.

Fig. 3 is a longitudinally vertical sectional View of the bed on the line 3-'3 of Fig. 2.

Fig. al is a top plan view of the bed.

Fig. 5 is a transverse vertical section on line of Fig. l, and

Fig. 6 is a detail perspective view of the shilitable section of the bed spring.

The preferred embodiment of my invention as illustrated in the accompanying drawings includes a bedstead comprising s indicated at 4 for ya purpose to be set lVith these and numerous other objects i which serves as Specicatonof Letters Patent. Putnted Julyo, Application filed October '8, 1917. Serial No. 195,385. i i i arms 2 terminating at points approximately midway the length of the side rails. For the purpose of providing space for pivotal con` nection and movementA of a head rest to Ybe described, a portion of the horizontal flan-ge at the end of each armis cut away and the vertical flange below the cut-away portion is provided with an aperture 3 waose purpose will be seen as the description progresses. The horizontal lflange from each cut-away portion to points spaced `from said cut-away portions are bent downwardly as forth.

Disposedvat the head of the `bed is n an U- shaped frame 5 forming a head rest, said provided adjacent their outer ends with ap ertures adapted to aline with apertures 3 and withy aperturesI in the, side rails R, said.

frames and side rails being connected to? `the like 6 which extend gether by bolts or through the alined aperturesV and pivotally connect the frame 2 to thebedstead and to the relatively stationary Vframe l, the head rest being movable about .the bolts 6, each Aof .a pivot. frame l5 I ,employ a length of angle metal of inverted L-shape -in transverse section, the end sections or overlapping ends being provided with alined In forming the arms being bent at rightV angles to the central section .8. and when in apertures through which rivets or the like Q fastening elements 9 pass toY retain the sections in proper relative position. The horizontal langeofeach arm 7 is slit'trans4` point adjacent the inner edge'Y horizontal ilange ofthe central sec- Y versely at a of the tion 8. The slits extend substantially onehalf. the width Vof the from said 'slits to the farther ends of the .flanges is bent downwardly at right angles lto formadditional flanges to coact withthe vertical flanges of the angle metal in formflanges, and the metal ing guideways 10 whose purpose Vwill be*` Y hereinafter set forth.

The two frames l and 5 are covered with a single strip of wire mesh fabric 11 which is secured at its ends to the closed ends of the frames Vand has itssides secured to theparallel arms 7 of theV head rest kframe 5 pivoted at one end and to those of the horizontal flanges of the arms 2, to t-he points where the latter [langes are bent downwardly, from which points to the pivotally connected ends of the arms, the edges of the fabric are left unattached, so that when the fabric between the unattached points will yield to a greater extent than the remaining fabric and will thus pro- Vide for comfortably conforming to the body of a person supported by the bed in a sitting position or in the recliningposture suggested by the position of the frame 5, in Fig. 3.

For the purpose of raising the head rest to the desired angle, a pair of curved levers 12 are pivotally connected intermediate their lengths to the side rails R, each lever having an anti-friction roller or shoe 13 on its upper end to be received in the adjacent guideway 10 on the head rest, and having in its other end an aperture for a purpose to be seen as the description progresses.

For `the purpose of operating the levers 12 and thereby adjusting the head rest, a windlass 14 is mounted on the outside of the foot section F, being vertically disposed and comprising a shaft 15 having its upper and lower ends mounted in bearings 16, the lower bearing being formed in the end of a casing tube 17 which incloses the shaft and is brazed or otherwise suitably secured to the cross bars of said foot section. The upper bearing for the shaft 15 is formed in a flat cap plate 18 which closes the upper end of the casing 17 and is of a diameter greater than that of the casing.

The cap plate 18 also provides an additional means of connection between the casing 17 and the foot section F, in that av portion of the ange overlaps the top cross-bar of said section and has laterally oppositely directed ears 19 which are brazed to said cross-bar. The upper end of the shaft eX- tends slightly above'the cap plate 18 and has non-rotatably mounted thereon an operating crank 20 and between said crank and plate a ratchet wheel or pinion 2l is mounted and adapted to be engaged by a pawl 22 which is to one of the attaching ears 19.

At a point near its lower end the casing 17 is slit vertically and has horizontal slits intersecting the upper and lower ends of the vertical slit, the metal on each side of the vertical slit being bent laterally outward to the cable upon the shaft, and transmitting motion to the levers; and, when the head rest is to be lowered, the crank is turned counter-clockwise to wind on the shaft, in an opposite direction to that of the cable 24, a cable 24 which has one end connected to the shaft and its other. end passed over a pulley 26 mounted on the head section substantially midway between the corner posts and connected to the closed end of the head rest.

From the foregoing description of the construction andY operation of my improved bed, the operation thereof, will be readily understood, but it is also to be understood that numerous changes in the minor details of construction may be made without sacrificing the principal advantages.

I claim: j

A bed having head and foot sections and an adjustable head rest; in combination with means for operating said rest including a vertical windlass and cables wound thereon and a vertical casing for said windlass formed of a single length of tube having bearings for said windlass and mounted on l.

the foot section, the lower end portion of said casing having'a vertical slit and a pair of horizontal slits intersecting the upper and lower ends ofsaid vertical slit, the metal on the opposite sides of said vertical slit being bent laterally outward to form spaced flanges between which said cables pass, an operating crank on the upper end of said windlass and a pawl and ratchet mechanism therefor.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses. Y A
